US-20260126109-A1 - PROTECTIVE COVER

Abstract

The heat shield member is used to protect the constant velocity joint extending in the direction of axis C, the heat shield member being made of a plate-shaped body and having an L-shape having two tip end portions when the heat shield member is unfolded in a direction perpendicular to the plate thickness direction of the plate-shaped body. The two tip end portions are provided with fastening portions each having a fastening hole, the heat shield member is configured to be mounted to the transfer in a cantilevered manner by fastening the respective fastening portions, and the cutout is provided at an edge end portion on a side of the heat shield member configured to be mounted in the cantilevered manner, the cutout being configured to suppress a localized concentration of stress due to a bending load generated in a cross-section orthogonal to a straight line connecting the fastening portions.

Claims (5)

1. 1 . A protective cover that is used to protect a rotating member extending in an axial direction, the protective cover being made of a plate-shaped body and being configured in an L-shape with two tip end portions when the protective cover is unfolded in a direction perpendicular to a plate thickness direction of the plate-shaped body, wherein: fastening portions are provided at the two tip end portions, respectively; the protective cover is configured to be mounted in a cantilevered manner by the fastening portions being fastened; and a cutout is provided at an edge end portion on a side of the protective cover that is to be mounted in the cantilevered manner, the cutout being configured to suppress a localized concentration of stress due to a bending load generated in a cross-section orthogonal to a straight line connecting the respective fastening portions.
2. 2 . The protective cover according to claim 1 , wherein, when the protective cover is unfolded in the direction perpendicular to the plate thickness direction, a curvature of an edge end of the cutout gradually changes at a location where the stress due to the bending load is generated.
3. 3 . The protective cover according to claim 1 , wherein: the protective cover includes a plurality of flat portions and a step portion configured to connect adjacent flat portions to each other among the flat portions; and the cutout is provided in the flat portion.
4. 4 . The protective cover according to claim 1 , wherein: the protective cover includes a plurality of flat portions and a step portion configured to connect adjacent flat portions to each other among the flat portions; and the cutout is provided by cutting out a root portion of the step portion in the flat portion.
5. 5 . The protective cover according to claim 1 , wherein the protective cover is configured to be mounted in the cantilevered manner by the fastening portions each being provided at a corresponding one of the two tip end portions.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to Japanese Patent Application No. 2024-194751 filed on November 6, 2024. The disclosure of the above-identified application, including the specification, drawings, and claims, is incorporated by reference herein in its entirety. BACKGROUND 1. Technical Field The present disclosure relates to a protective cover that is used to protect a rotating member extending in an axial direction. The protective cover is made of a plate-shaped body and is configured in an L-shape having two tip end portions when the protective cover is unfolded in a direction perpendicular to a plate thickness direction of the plate-shaped body. 2. Description of Related Art A protective cover is known that is configured to be mounted in a cantilevered manner such that a first end portion is fixed to a transfer and a second end portion is a free end. For example, the protective cover is described in Japanese Unexamined Patent Application Publication No. 2021-000862 (JP 2021-000862 A). The protective cover described in JP 2021-000862 A is provided to extend along an axis and has a semi-cylindrical shape with a semicircular cross-section, in which half of the protective cover is open in a circumferential direction. The protective cover is supported by a bearing provided between the first end portion fixed to the transfer and the second end portion that is a free end. SUMMARY By the way, there is a case in which a protective cover that is used to protect a rotating member extending in an axial direction is desired to be made of a plate-shaped body and be configured in an L-shape having two tip end portions when the protective cover is unfolded in a direction perpendicular to a plate thickness direction of the plate-shaped body. In such a case, a structure in which the protective cover is supported by the bearing such as the protective cover of JP 2021-000862 A cannot be adopted. As a result, in the protective cover having the structure in which the protective cover is mounted in the cantilevered manner, there is a possibility that the protective cover is damaged due to a localized concentration of stress due to a bending load. The present disclosure is made in view of the above circumstances, and an object of the present disclosure is to provide a protective cover that has a structure mounted in a cantilevered manner, and is capable of suppressing damage due to a localized concentration of stress due to a bending load. The gist of the present disclosure is a protective cover that is used to protect a rotating member extending in an axial direction, the protective cover being made of a plate-shaped body and being configured in an L-shape with two tip end portions when the protective cover is unfolded in a direction perpendicular to a plate thickness direction of the plate-shaped body, in which: fastening portions are provided at the two tip end portions of the protective cover, respectively; the protective cover is configured to be mounted in a cantilevered manner by the fastening portions being fastened; and a cutout is provided at an edge end portion on a side of the protective cover that is to be mounted in the cantilevered manner, the cutout being configured to suppress a localized concentration of stress due to a bending load generated in a cross-section orthogonal to a straight line connecting the respective fastening portions. With the protective cover according to the present disclosure, the fastening portions are provided at the two tip end portions of the protective cover, respectively, the protective cover is configured to be mounted in the cantilevered manner by the fastening portions being fastened, and the cutout is provided at the edge end portion on the side of the protective cover that is to be mounted in the cantilevered manner, the cutout being configured to suppress the localized concentration of the stress due to the bending load generated in the cross-section orthogonal to the straight line connecting the respective fastening portions. As described above, in the protective cover having the structure in which the protective cover is mounted in the cantilevered manner, the cutout is provided, thereby suppressing the localized concentration of the stress due to the bending load and suppressing the damage to the protective cover.
